SASH-BALANCE.

ESPECIPICATION forming part of Letters Patent No. 321,871, dated J'u1y'7, 1885.

Application filed April 30, 1885. (No model.)

To all whom it may concern:

Be it known that 1,,AUGUST WERNER, a

I citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Sash-Supports, of which the following is a specification.

My invention relates to improvements in sash-supports; and it consists in the novel construction and arrangement of parts, all of which is fully pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which Figure 1 is a front elevation, part in section, of my improved sash-support applied to a window-frame and sash. Fig. 2 is a central vertical section of the same.

Similarletters indicate corresponding parts.

In the drawings, the letter A designates the window-frame of any ordinary construction, and B is one of the sashes fitted into the frame in the usual manner. Over the top of the frame are two pulleys, O O, rigidly mounted on a suitable shaft, D, which has its bearings at a a in an upright hanger, E, secured to the frame. The sash B is connected with the pulleys by cords b b, which are attached to the upper partof the former in the usual manner and are firmly secured to the pulleys, so that when the sash is drawn downward the pulleys will be rotated.

F is a helical spring possessing the suitable strength for the purpose, which surrounds the shaft D, extending over the greater part of the length of the same. This spring is attached at one end, 0, Fig. 1, to the shaft, and

at its other end, 0, it is secured to the upright hanger E, so that when the sash is lowered the spring will be subjected to a torsional stress, and by using a spring possessing the proper degree of flexibility the sash will be sustained in any position to which it may be raised orlowered by the reaction of said spring.

It will appear evident that the same result would be produced if the shaft D did not extend completely across the hanger E-that is to say, if each of the pulleys G C were mounted on a separate short shaft or pintle and the spring F were attached at one of its ends to the hanger at c, as before, and its opposite end, a, to one of the short shafts or pintles; however, the device can be more easily made and possesses greater strength when the first method is followed.

In order to secure the sash immovably at g any point I use a rack, G, secured in a suitable longitudinal recess, d, in the windowframe in position to be engaged by the pin 6, which fits in a recess, 9, in the sash-frame and is subjected to the action of a spring, h, which abuts against the end of the recess 9 and against a shoulder formed 011 the pin, so that the pin constantly engages the rack, and the sash can only be moved when the pin is withdrawn.

Instead of having separate pulleys O G the shaft and pulleys may be made integral or the shaft 'may be made larger in diameter at its ends and the sash-cords be directly attached to the enlarged ends of the shaft.

I am aware that a sash-balance has heretofore been composed of a roller journaled at the top of the window-frame and connected by cords with a sash, a convolnte spring being wound around the roller and connected at its inner end thereto and provided at its outer end with a staple driven'into the windowframe. Such, however. does not constitute my invention, and is not claimed by me.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of a window-frame, A, a sash, B, the bearings c c, the shaft D, mounted in the bearings, and the cords connected with the sash and shaft, with the spring F, wound spirally along the length of the shaft and having one end secured thereto adjacent v to the bearing a and the opposite end secured directly to the bearing 0 which supports the shaft, substantially as described.

2. The combination, substantially as hereinbefore described, with the windowframe and sash, of the shaft having bearings in a suitable hanger, the pulleys mounted on the shaft, the cords attached to the pulleys and the sash, the spring surrounding the shaft and attached at one end to the same, its other end being attached to the hanger, the rack G, and the spring-pressed pin 6, constructed to engage the rack.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
